What is the beta agonist?
Agonist is a medicine that is used to relax the muscles of bronchial tubes to stimulate the heart muscle in the expansion of the blood vessels. Beta agonist interacts with beta-2 receptors on muscle cell surfaces, causing relaxation in smooth muscle cells in bronchial tubes or stimulating in heart muscle cells. When used as a bronchodilator, medications can be used orally, but are often served as an inhaler or spray fog. If the desired effect includes heart muscles, it must be administered as intravenous injections.
After branching from the trachea, the bronchial tube is divided into ever smaller airways leading to alveoli, ie small bags in the lungs that perform oxygen and carbon dioxide. During asthma attacks or chronic obstructive lung disease (COPD), the muscles of the bronchial tubes are limited and then cannot relax. The volume of air passing through it into the lungs can be so limited that the body is no longer capable ofget the oxygen it needs. The level of carbon dioxide in the blood also rises to a dangerous level that can cause loss of consciousness. The beta agonist works to relax the muscles in the airways and opens the bronchial tubes to allow more air flow.
In cardiac muscle cells, agonist beta stimulates increased calcium absorption, producing stronger contractions in every muscle cell and increasing heart rate. It also allows the muscles to relax faster and the signals from pacemakers quickly pass through the heart. When Agonist Beta is used to treat symptoms of heart disease, the effect is an important effect for the rest of the circulatory system. Because the beta agonist causes relaxation of the walls of blood vessels, this leads to dilatation that helps maintain a btlak lood from too much climb in response to a higher blood flow.
oral beta agonists who act on a bronchial testKy, they are usually available in several forms such as syrups, tablets, nebulizer solution and injections. Epinephrine, norepinephrine and dopamine are examples of beta agonists who treat heart conditions and are injected into the bloodstream. Other applications for beta agonists include stopping contractions in early work, stimulating the liver to decompose glucose and causing renal release and pancreas. Possible side effects include tremor, headaches, arrhythmias and anxiety.
